Contact Lenses of the Future Will Treat Your Eye Diseases

The World Health Organization estimates that glaucoma is the second lead cause of cecity worldwide . And though the first lead cause of cecity – cataract – can be treated with operating room , the blindness triggered by glaucoma ca n’t be for good cured . That ’s why Tingrui Pan and Hailin Cong , researchers at UC Davis , have plan a middleman lens that keep tablet on the disease all by itself . And they ’re play up to one that dispenses medication mechanically , too . Their “ smart ” lenses are tally with an constitutive polymer called polydimethylsiloxane ( PDMS ) , which is commonly used in biologic program . Since glaucoma develops as a resolution of raised pressure inside the centre , the finish of the lenses is to detect that intraocular imperativeness and mark word of advice signs . Up until now , though , PDMS has n’t been used as a sensor of anything , since the creation of sensor circuits requires conduction — and PDMS does n’t have that . Pan and Cong , however , found a way to make conductive composites of PDMS and apply them to contact lens lens , and thus a insistence - feel manner statement was born . With these smart genus Lens , patients wo n’t have to rely on visits to the doctor to check their intraocular pressure . The sensors on top of their center will be doing it all by themselves , and sending the data to a computing machine to boot .

“ It ’s very different from billet like cardiac disease or diabetes , where patients can bust devices that evaluate heart rate or blood pressure 24 hours a day for a week or more to get a better idea of what ’s going on , ” sound out James Brandt , a prof of ophthalmology at UC Davis and Pan ’s partner in crime . “ We do n’t have that for glaucoma , and that ’s one of the biggest clinical frustrations we have . ”

Pan and Cong will be team up with Brandt to begin tribulation of the bright contact lenses in humanity . This is n’t the first link lens with a circuit — a University of Washington team managed toembed light-emitting diode into a lens of the eye in pursuit of superhuman vision — but this is the first with direct app program toward treating a disease . No watchword yet on whether that PDMS complex is really , really annoying to seek and see through , however .
